نبذة مختصرة : The objective of the study was to evaluate the maternal intention to breastfeed, duration of the breastfeeding and reasons for weaning among mothers and babies from southern Brazil participating in a multi center study. This is a cohort study conducted in Pelotas, RS, with participants from the Multi-Centre Body Composition Study. Mothers and babies were enrolledat the hospital of delivery and were followed-up at 3, 6, 9, 12, 18 and 24 months of age. The reasons for weaning before 12 months were investigated. Median and interquartile intervals of breastfeeding duration were calculated. Of the 1377 mothers screened, 74% intended to exclusively breastfeed until 6 months and 91% to prolong the breastfeeding until at least 12 months. A total of 168 mother-child pairsmetall eligibility criteria and agreed to participate in the follow-up. The median of the breastfeeding duration was 11 months (IQR: 5.8-23.0 months), and 52% of the infants were weaned before 12 months. The main reasons for weaning were insufficient milk (57%), return to work/school (45%) and unexplained refusal of the baby (40%). The results showed that despite the intention to breastfeed, there is a need to clarify the mothers and families about issues related to breastfeeding. ; Conselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPq ; O objetivo do estudo foi avaliar a intenção materna de amamentar, duração do aleitamento materno e os motivos para o desmame entre mães e bebês do sul do Brasil participantes de um estudo multicêntrico.
